This invention relates to fasteners and by firmly Securing the members together particularly to those of the snap type whereagainst possible displacement. The outer in one element of the fastener is permanentwall 14 of the member 10 is preferably of ly secured to one article, and the other eleits greatest diameter near the top 15 therement ofthe fastener to another article, whereof, being curved slightly inwardly toward 55 by the articles may be removably secured tothe bottom and Where it meets the innermost gether through the detachable engagement part of the flange 12, being shaped toV form of the fastener elements. a groove 16 of sufficient height to receive the My invention contemplat'esthe provision edge 17 of the aperture 18 formed in the of a fastener element usabl-e either as a stud member 19, such as the thin sheet to which' eov member or as a socket member and which the element'is to be attached. may be secured in place permanently or de- In order to form the inner wall 21 of the tachably, as desired, with a minimum of member 10, spaced inwardly from the outer labor.

Said In that practical embodiment of my inveninner wall is formed by bending back the-9,0 tion which I have illustrated by way of eX- end of the member 11 inside of the outer wall ample, I prefer to make my improved fas- 27 thereof. Said outer wall 27 of the engagtener element of two pieces of material, nameing member 11 is preferably provided with ly, of a hollow, slotted member 10, which I a groove 28 at the juncture thereof with the will refer to hereinafter as the clinching shoulder for thereception of the yieldable 95 member, and a hollow engaging member 11. member of a socket element of any well The clinching member 10 terminates in a known type, the member 11 preferably servprojecting fiange as 12 (Fig. 3) and the meming as a stud element of a snap fastener. ber 11 terminates in a projecting shoulder It will be understood, however, that the or rim 13 bent over the fiange 12 and theremember 11 may be used as a socket element, lOf` if desired, sufiicient space being left below the end 26 of the Wall 25 to receive a suitable stud.

lVhen it is desired to secure my improved fastener element permanently in place, as for instance, to the sheet 19, which may be partof the body or of the Wind-shield of an automobile, the reentrant portion 23 of the clinching member 10 may be pushed out toward the top edge 15 of said member after the element has been pushed through the aperture 18. rThis may be done by means of a suitably Shaped tool as 30, shown in dotted lines in Fig. 4:; The shoulder or rim 13 engagesthe face 31 of the sheet 19 and holds the element against displa'cement during the clinching operation, and also serves as astop to limit the inserting movement of the element through the aperture 18. The tool 30 is pressed against the depressed portion and moved axially of the element Whereby the member 10 issomewhat distorted, the member bending` about the edge 17 of the aperture 18 and the yieldable sections 24 being sulfioiently increased in diameter to bind tightly against the edge 17 Allpossibility of looseness or rattling 'of the element in the aperture 18 is thereby prevented.

It Will be understood that While I have shown and described preferred embodiment of my invention7 I do not Wish or intend to limit myself thereto, but intend to claim my invention as broadly as may be permitted by the state of the prior art and the scope of the appended claim.

I claim:

In a fastener installation, a support, a rigid Wall surrounding an aperture in the support, a two-piece fastener element comprising a yieldable clinching member having an outer Wall and a depressed inner Wallv closed at the bottom and spaced from the outer Wall and continuous therewith, said member being provided With spaced radial slots passing through the upper part of both of said Walls, and forming yieldable sections between said slots7 an annular fiange at the edge of said outer Wall,'the juncture of said flange and the outer Wall being shaped to provide a groove, the least diameter of said groove being` less than any outer diameter of saidouter Wall, an engaging member having an outer Wall and a depressed apert-ured inner Wall spaced from the outer Wall, and a terminal shoulder on said engag'ing member bent about the flange of the clinching member and holding said clinching member in place7 the clinching member being adapted to be forced through the aperture in the support Whereby the Wall of the aperture first forces the yieldable sections invvardly and finally rests in the groove of the clinching member and against the shoulder, the diameter of the shoulder being greater than that of the engaging member for that purpose,

nevaier said yieldable sections expanding after passage through said opening and resisting the withdrawal of said clinching member back through said opening, and said depressed and slotted inner Wall of the clinching member being movable outwardly by a tool inserted through the aperture of the engaging member into direct engagement with said lastmentioned Wall to increase the diameter of the yieldable sections permanently and thereby to deepen said groove.
